can someone help me - i am new to forum. i do not have a physics background - medical doctor. i have been looking on the net to answer a simple question - what is the accepted shape of the known universe? if the big bang is correct, then is it accepted that the universe is basically is the expanding outside layer of a sphere? - like the peel of an apple/orange. if so then what becomes of the inside of this sphere? is it a vacuum or it is it nothing at all as in it does not exist - can light travel through it. can a spacecraft fly through it? if the inside space does not exist then is it actually possible to see parts of the universe on the opposite side of the sphere.
also, if the universe is the outside layer of a sphere then is it true that if you travel in one direction continuously then you will end back in the same position?
these questions have been bothering me for ages and i can't find any answers or maybe there are but i cannot understand them.
